Description
Technical field
The utility model, which belongs to, is related to a kind of bearing driving component, is a kind of bearing shell specifically.
Background technique
Bearing shell is a kind of bearing components, is the part of sliding bearing and axis contact, very smooth, general to use bronze, subtract
The wear-resistant materials such as alloy that rub support, also referred to as " bushing ", shape are the semicircular ring of tiles.Oil is typically provided on bearing shell
Slot, to reinforce storage of the bearing shell to lubricating oil, main shaft is during rotation in oil groove and lubrication that oil groove is spread to periphery
Oil is oppressed and is carried, so that lubricating oil sufficiently to be spread to the effect that lubricating oil film between main shaft and bearing shell reaches guard block
Fruit.And lubricating oil addition is generally additionally provided with fuel feed hole in oil groove, on bearing shell for convenience, fuel feed hole is connected to oil groove；
But the presence of fuel feed hole is also easy the oil leakage in oil groove, and the ability that contains of oil groove is made to receive reduction largely,
Increase the number of topping-up.
Utility model content
The utility model aim is intended to provide a kind of not easy oil leakage, and more conducively main shaft axis that lubricating oil is taken out of to oil groove
Watt.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of bearing shell, including in semicircle shape top bearing shell and and lower bearing, the lower bearing dock to form axis with top bearing shell
Watt entirety；The middle position of the top bearing shell medial surface along the circumferential direction offers oil groove from one end to the other end；The upper axis
Tangential direction on watt along oil groove offers the fuel feed hole being connected to oil groove；At least side of the oil groove is provided at least two
Branch oil groove, and branch oil groove is along the radial equipartition of oil groove；One end of the branch oil groove is connected to oil groove, and the other end is located at top bearing shell side
The inside of edge；The branch oil groove favours oil groove along the oil inlet direction of fuel feed hole.
Further, the middle position of the lower bearing medial surface offers lower oil groove identical with oil groove, works as lower bearing
When docking to form bearing shell entirety with top bearing shell, lower oil groove docks to form annular groove with oil groove, can more oil storages.
Utility model by adopting the above technical scheme,
It further limits, the section semicircular in shape of the oil groove.
It further limits, the rectangular in cross-section of the branch oil groove.
It further limits, the groove depth of the branch oil groove is gradually decreased as zero to the other end from the one end being connected to oil groove, makes
Main shaft takes the lubricating oil in branch oil groove out of more smooth.
It further limits, the tilt angle of branch oil groove is 60 degree.
It further limits, is provided with retention Hp on top bearing shell and lower bearing, the installation of bearing shell can be facilitated.
The utility model is compared when having the advantage that more compared with prior art, and fuel feed hole is transverse to oil groove, during installation, makes
The oil inlet direction of fuel feed hole is cut in main shaft along the rotation direction of main shaft, and under the rotation of main shaft, what lubricating oil can be fast fills up oil
Slot, and since the rotation of main shaft can reduce lubricating oil to lubricating oil one trend to bearing shell internal flow in fuel feed hole
The risk flowed out by fuel feed hole, the oil storage performance of the oil groove of raising, and branch oil groove favours oil along the oil inlet direction of fuel feed hole
Slot enables the lubricating oil in branch oil groove more to contact with main shaft, and main shaft is enable more successfully to take lubricating oil out of branch oil groove
And reach preferably lubricant effect.
Detailed description of the invention
The utility model can be further illustrated by the nonlimiting examples that attached drawing provides；
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the top bearing shell of the utility model；
Fig. 3 is the structural schematic diagram of the lower bearing of the utility model；
Fig. 4 is the sectional view of the top bearing shell of the utility model；
Main element symbol description is as follows: 1, top bearing shell；2, lower bearing；3, oil groove；4, fuel feed hole；5, branch oil groove；6, under
Oil groove；7, retention Hp.
Specific embodiment
It is right with reference to the accompanying drawings and examples in order to make those skilled in the art that the utility model may be better understood
Technical solutions of the utility model further illustrate.
Referring to attached drawing 1 to 4, one of figure bearing shell docks formation including the top bearing shell 1 in semicircle shape and with top bearing shell 1
The lower bearing 2 of bearing shell entirety along the circumferential direction offers oil groove from one end to the other end in the middle position of 1 medial surface of top bearing shell
3, oil groove 3 is semicircle for storing lubricating oil, preferred 3 section of oil groove of this implementation；Along the tangent line side of oil groove 3 on top bearing shell 1
To fuel feed hole 4 is offered, fuel feed hole 4 is connected to oil groove 3, which is circular hole, and the radius of 4 section of fuel feed hole circle is equal to
The radius of the section semicircle of oil groove 3, and on the section perpendicular to 4 tangent line of fuel feed hole, the section semicircle of oil groove 3 overlaps oil inlet
On the circle of 4 section of hole；Being evenly equipped at least two branch oil grooves 5, the section of branch oil groove 5 in at least side of oil groove 3 is preferably rectangle, should
